Hello, I’m considering upgrade of my 4,1 Mac Pro (upgraded and flashed to 5.1) but I’m not sure if my GTX 970 will be still working after upgrade. That is the only reason I didn’t upgraded it yet. I don’t have an original GPU. What do you recommend doing in that situation? Thanks in advance for any help
Hello Maciek, I have the same Mac Pro, only with a GTX 1060. From what i saw, there are macOS Cuda drivers for macOS 10.13.x ( http://www.nvidia.com/object/macosx-cuda… ) and the drivers for the Quadro and Geforce GPU’s ( http://www.nvidia.com/download/driverRes… ). So practically, yes you can install the new macOS High Sierra. The only problem is that when you upgrade it, I don’t think that the GPU is going to work until you install the drivers, so it’s “safer” for you to do it with a stock GPU. It might work, but I’m not totally sure, because I never tried to do it.
Hi. You can pick up the default nvidia Gfx GT120 on ebay for super cheap these days. I keep one handy just in case I need to get to the pre-boot screen. There are better cards that support pre-boot and even Metal, but this one is super handy for slapping in when I just need video to boot because of some other issue. Even Mojave will boot with this graphics card provided you installed it with a metal supported one at the time. Not a full answer but a tip for sure.
